The MCP2515 implements CAN 2.0B with 3 transmit buffers and 2 receive buffers, accessed via SPI. It runs at 2.7V-5.5V in DIP-18/SOIC-18 and is often paired with MCP2551 transceiver.
CAN bus nodes for vehicle telematics, marine electronics, industrial machinery and hobby projects (e.g., Arduino CAN shields).
The SPI interface frees MCU resources; configure bit timing registers for the target baud rate (typically 500kbps). Use a CAN transceiver on CANH/CANL.
